@Deprecated
public class SequenceHiLoGenerator
extends SequenceGenerator

seqhilo

An IdentifierGenerator that combines a hi/lo algorithm with an underlying oracle-style sequence that generates hi values. The user may specify a maximum lo value to determine how often new hi values are fetched.

Mapping parameters supported: sequence, max_lo, parameters.

Method Detail

configure

public void configure(Type type,
                      Properties params,
                      ServiceRegistry serviceRegistry)
               throws MappingException

Deprecated.

Description copied from interface: IdentifierGenerator

Configure this instance, given the value of parameters specified by the user as <param> elements.

This method is called just once, following instantiation, and before IdentifierGenerator.registerExportables(Database).

Specified by:

configure in interface Configurable

Specified by:

configure in interface IdentifierGenerator

Overrides:

configure in class SequenceGenerator

Parameters:

type - The id property type descriptor

params - param values, keyed by parameter name

serviceRegistry - Access to service that may be needed.

Throws:

MappingException - If configuration fails.

generate

public Serializable generate(SharedSessionContractImplementor session,
                             Object obj)

Deprecated.

Description copied from interface: IdentifierGenerator

Generate a new identifier.

Specified by:

generate in interface IdentifierGenerator

Overrides:

generate in class SequenceGenerator

Parameters:

session - The session from which the request originates

obj - the entity or collection (idbag) for which the id is being generated

Returns:

a new identifier
